GRAIN- DRILL.

SPECIFICATION forming part of Letters Patent No. 440,182, dated November 11, 1890.

Application filed May 26, 1890.

To all whom it may concern.-

Be it known that I, MILTON PHILANDER MOTTER, a citizen of the United States, residing at Oswego, in the county of Labette and State of Kansas, have invented a new and useful Grain-Drill, of which the following is a specification.

This invention has relation to improvements in grain-drills, and especially to the flexible tube usually employed leading from the hopper or hoppers to the drill tube or boot.

Heretofore difficulty has been experienced by reason of the necessarily-employed flexible tubes leading from the hopper or hoppers to the drill-boot becoming bent and stopping the flow of grain and from the flexible tubes leaving the drill-tubes by reason of the latter meeting with obstructions during the process of drilling grain.

The object therefore of my invention is to provide means for avoiding the above objections and at the same time to preserve the necessary and advantageous flexibility of the grain tubes.

With the above objects in view the invention consists in introducing into the upper end of each tube a spring-steel rod adapted to maintain the tube perfectly straight and at the same time not interfere with its flexibility and provide means for supporting the rod centrally within said tube.

Referring to the drawings, Figure 1 is a perspective view of a drill and seed tube provided with my invention. Fig. 2 is a vertical longitudinal section of the same.

Like numerals of reference indicate like parts in both figures of the drawings.

1 represents the hopper, and 2 the drilltubes or drill-boots, which latter are supported under the hopper by the usual hinged supporting-arms 3, which, asisusual,are yieldingly supported in position.

4. designates the flexible seed-tube, connected at its upper end to the hopper and at its lower end to the drill tube or boot.

5 represents a spring-steel rod, of a length equal to the grain-tube 4, and said rod is pro- Serial No. 353,257. (No model.)

vided at its upper end with a head 6, also adapted to serve as a handle for withdrawing v the rod. The upper end of the grain-tube is flared in the usual manner, forming a head 7, and in the same rests the head 6 of the rod. The latter head being the larger is therefore supported by the former head in a central position with relation to the grain-tube.

From the above construction it will be apparent that it will be impossible for the tube 5 to become bent to such an extent as to choke or prevent the ready feeding of the seed or withdrawal of itself from the upper end of the drill-tube or for the drill-tube to have any movement capable of disconnecting itself from the lower end of the flexible tube. The head 6 of the rod, besides serving as a means for supporting the rod in position, also constitutes a ready handle by which the rod may be grasped and withdrawn, as will be apparent. The steel rods permit the tubes to be bent and readily yield and promptly return them to position after such bending.

Having thus described my invention, what I claim is- 1. The combination, with a flexible graintube, of a resilient rod mounted in said tube, substantially as specified.

2. The combination, with a-fiexible graintube and a graindrill boot receiving the lower end of the same, of a resilient rod terminating at its upper end in a head resting upon the upper end of the grain-tube and depending withinthe same, substantially as specified.

3. The combination, with the flexible graintube 2, its supporting-arm 3, and the grain-drill tube 4, having the head 7, of the resilient rod 5, terminating at its upper end in the combined handle and head 6, substantially as specified.

In testimony that I claim the foregoing as my own Ihave hereto affixed my signature in presence of two witnesses.

MILTON PHILANDER MOTTER.
